Description

When volume_prefix begins with "/", the library will try to stat the empty string resulting in a log like:

2021-07-01 02:15:04.449 7f7612b5ab80  3 client.178735 statx enter (relpath  want 2047)
/usr/include/c++/8/string_view:172: constexpr const _CharT& std::basic_string_view<_CharT, _Traits>::operator[](std::basic_string_view<_CharT, _Traits>::size_type) const [with _CharT = char$_Traits = std::char_traits<char>; std::basic_string_view<_CharT, _Traits>::size_type = long unsigned int]: Assertion '__pos < this->_M_len' failed.
Aborted (core dumped)

relpath indicates the empty string.
